Cleaning the Condenser Coils
Clean the coils at least once a year or more frequently if unit is located in a dusty and dirty environment, in order to
maintain your system's proper operating performance. High discharge pressures are good indication that the coils need
cleaning. When using detergent or solvents to clean the coils, follow the manufacturer's instructions to avoid potential
damage to the coils and to the unit.
To clean the refrigerant coils, use a soft brush and water spray, such as garden hose or pressure washer with low pressure
nozzle.
WARNING
Do Not Use High Alkaline Detergent!
When using detergent for coil cleaning, ensure that the alkaline level is no higher than 8.5, which can cause corrosion damage
to the coils.
No Water into the Electrical Compartments!
Ensure consideration is given to the possibility of water entering the electrical compartments during cleaning of the
condenser coil.
